About Us
Crafting digital trust with our Photoshop Detector.
Our Mission
In an era of deepfakes and generative AI, verifying the authenticity of a photograph has become genuinely difficult. The Photoshop Detector exists to give anyone — journalists, researchers, or curious individuals — a free, no-account-required tool for a first-pass integrity check on any image.
How We Analyse Images
We combine two independent techniques for each upload:
- Error Level Analysis (ELA) — re-compresses the image at a known JPEG quality and measures pixel-level differences. Edited regions typically compress at a different rate than untouched areas, revealing themselves as bright patches in the heatmap.
- LBPH Machine Learning — a Local Binary Pattern Histogram model trained to distinguish authentic photographs from AI-generated or heavily retouched images.
Results from both methods are combined into a single verdict. The ELA heatmap is always shown so you can make your own judgment.
Privacy
Uploaded images are held in temporary storage for a maximum of 20 minutes and then permanently deleted. We do not train on your uploads, share them, or retain them for any purpose. See our Privacy Policy for full details.
Limitations
No automated tool can replace expert forensic analysis. ELA and LBPH are probabilistic indicators — not definitive proof. A clean result does not guarantee an image is authentic, and a flagged result does not prove it has been manipulated. Use our tool as one signal among many.
